    Built for optimum NAS compatibility
    Our exclusive advanced firmware Desktop drives aren't purposebuilt for NAS. But WD Red drives with NASware are. Our exclusive technology takes the guesswork out of selecting a drive. WD Red is for small NAS systems, and our unique algorithm balances performance and reliability in NAS and RAID environments. Simply put, WD Red is the most compatible drive available for NAS enclosures. But don't take our word for it. WD Red is a reflection of the most extensive NAS partner compatibility-testing list that is available on the market.

    Desktop drives vs. WD Red
    In a Network Attached Storage device, a desktop hard drive is not designed for NAS environments. Do right by your NAS and choose the drive with an array of features to preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS:

    • Compatibility: Without being tested for compatibility with your NAS system, optimum performance is not guaranteed.
    • Reliability: The always-on environment of a NAS or RAID is a hot one. And desktop drives aren't typically designed and tested in those conditions. WD Red is.
    • Error recovery Controls: WD Red NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. Desktop drives are typically not designed for RAID environments where this can be an issue.
    • Noise and Vibration Protection: Designed to operate solo, desktop drives offer little or no protection from the noise and vibration faced in a multi-drive system. WD Red drives are designed for multi-bay NAS systems.

    WD Red for Home
    Stream, backup, share and organize your digital content at home with a NAS and WD Red drives designed to effortlessly share content to the devices in your home. Red NASware increases your drives' compatibility with your devices, TV, stereo and more. Live in a connected world.

    WD Red for Small Business
    Businesses thrive on productivity and efficiency - two of the guiding principles built into the design of WD Red. It's the hard drive of choice for 1 to 8 bay systems. NASware 3.0 allows for seamless integration with your existing network so WD Red can share and backup files at the speed of your business. And for larger businesses with up to 16 bays, count on WD Red Pro.

    WD Red Pro for Big Business
    If you're looking for maximum performance in a heavy use NAS, WD Red Pro delivers the same exceptional performance for the business customer. For NAS environments with 8 to 16 bays, WD Red Pro is designed to handle an increase in workload and comes with a 5-year limited warranty.
